摘要
Professor Dang Sheng Su passed away on June 22,2019 at the age of only 58 years with a great loss for all the communities of catalysis,carbon materials and electron microscopy.He pioneered the study of metal-free nanocarbon as high-performance catalysts and electrocatalysts,providing great advances in understanding the reaction mechanism and the nature of the active sites.He also largely contributed to the advances in characterization of nanomaterials by electron microscopy methods.
